The machine hereinafter set forth is of the type shown in the patent to F rank S. tosc. No. 'faellt-2, patented March 8th, lfllt. in which the carriage is adapted to he folded overahove the keys, and while in the present'invention the carriage and platen and thelroperatmg mechanisms are adapted to he raised and lowered on the frame of the machine and to he folded over above the nager keys. and 1n winch the type-hars have a front strike for visible writing, it is to be understood that many of the features of this invention may he used in connection with other classes of machines.

The metallic frame 1 of the machine is constructed and arranged in any suitable manner. and may consist of side members and an integral hack member with an intermediate transverse horiZontal har 2 suitably fastened to the sides of the frame and servin cr as a hrace therefor. and a second transverse har 2 at the front of the machine, the whole frame being constructed of sheet metal with rounded edges for the purpose of making;` the frame light and strong.

The key-levers 3. Fig. 1, may have 1I{eys or finger-pieces 4 forming a part of a universal keyboard, and are each provided intermediate its end with van upwardly-extending part This part 5 forms a head or suspending` member which engages the "ansversely-extending bars 1i located under the plate 2 and which serve to pivotally` sup` port the said keydevers. These levers are each forced in one'direction by a'spring 16, one end of which is held to a transverse bar 18 and at their inner ends the said levers are .connected b v links 19 to the type-bars Q0. lllach type-bar is pivotallgIv held at Elv toy a bracket and at its outer end is provided with a type-head having characters 30,

31, and 32 thereon which are adapted to be Afixed support or bed rlflie ineinber 39 is provided with grooves leiigthivise thereof atl -its under side, as sity-l0, and the support 3S is provided with grooves all on its iippersur- .face opposed tothe grooves-O so as to form race-wa-vson opposite sides of said member, and in the race-Ways are arranged balls l2 forming'a bearing for the member 39 or" the. carriage. As (sho, vn there are tivo balls in the outer race-Way, and one inthe inner i'aceiva'y, and each ball may be held in a circular guide k3 which surrounds the saine and normali;r rests 'on the member 38 adjacent to the grooves forming a. part of each race-way, said guides being connected together by a 1vire 43a to hold the balls prop-` erly spaced apart and to move' together. The carriage 3,6 is provided ith suitable guides.

as for 'example headed studs not shown, and

substantially L-shaped `brackets or gibs 45 and i6 are also fastened to the iixed. member '-38, the said bracket i6 being provided. with an adjustment screwY extending over the` member 39 of the carriage'as shown best in Fig. .1. The carriage when released, as will be hereinafter described, is moved forward for letter-spacing by a spring 4:8 arranged in a/drum 49, Figs.` l, 7 andl, onecnd "of which is held to a disk 5l b v which the spring may bevvoiind, and the other en d vto the drum 19, and both the di'ii-in and disk are rotatably supported cna shaft 52.over a I bracket 53. The disk 51 is provided ivi-th finger parts 54 and to said disk is pivoted a pavvl 55. This pavvl 55 is provided with two teeth 56 and 57, the latter of which is on a handle portion 5S of saidpavvl, and both teeth are adapted to engagea `fixed ratchet Wheel 59, bv which said disk may be held in an adjusted position and 4released by a. stepbysstep movement as desired. A flexible connection 59a is carried by the drinn and is held at one end to the drinn it?) and its other end extends fromthe d rnm aroundl a piillev or sheave located on thebed or support ot the carriage, and its other end is 'astened to the carriage so that when the carriage'is released the tension o fthe spring will force the same along said bed or support.

The parte thus far described may hebt the character shown or of any preferred form.

:is a means for letter-,spacing the carriage,`

l einplov a special construction `of escape ment, also a certain kindof escapenient in connection With' a special kind of typevvri'tl ing machine. As shown the carriage is prof vided with a rack-bar Which extends lciigti'iivise of the carriage yand meshing with said rack-bar is a pinion 71, Fig. l, and this pinion is held to rotate on a shaft 7i? pro# jectiiig iinder the carriage b'ed'oi' support 38 to thelower end of which is held a ratchet Wheel 73. This ratchet Wheel 73'f0rin`s a part of tl'ieescapement mechanism and isV located above 'the bracket oi plate v73a in which one end of the shaft 72 is j oiiiiialed, the ratchet ivheel 73 being held, to rotate With the shaft 7 2, and adapted to engage the ratchet wheelis an escapement devicev or 'lever 74e.,- This lever or device 74 comprises two parts or members 7 5 and 76,*,and carried. 'bv the member or part 7 6 are the paivls orv dogs 77 `and 78 the former of which is fixed and the latter loose, and said pawls are -adapted-to alternatei)v engage the teeth of the ratchet Wheel 73 to' permit said ratchet Wheel to rotate with a stepbv-step morement. The carriage is moved in one direcrtion b v the spring 48 andthe increment of the carriage transmits a rotary movement to the ratchet wheel 73thioiigli the rack-bar "70 and pinion l. The member 7 6 of. the espivoted intermediate the ends thereof vat 79 vto move horizontally above the bracket 73?.

Bv constriictingthe lever 74: and arranging the pawls or dogs as shown, the said parvis are caused to move directlv into andout of engagement 'With the ratchet 'Wheel Without a sliding movement, 'thus inateriallv*"over` coming the Wear andeiecting better alinei ment in letter-spacing. The paivl 7 Sis pivoted at S0, and is noriiiallv forced against a'.

pin 81 by means of a'spriiig 83-'and mavbe liniitied in its movement bv a vscrevs7 y84 so as tor be properlv lconned inits movement between the end of said screw and said pinv 8l. The niembei176 is normally forced to cause the pai'vl 78 to enga-ge al tooth of the ratchet scf icc

-capement lever is forced in ohe ,direction b v ,K a spring 76, and said escapeme'nt leiei is Wheel 7 3 by means of the spi'in'gi'a one end of which is fastened to lthey bracket 73a and the otherend to said member. there being a small fiat spring 84a, Fig. 5. having itsfiee end extending in the path of said ratchet Wheel topi-event backward -n'iovement or back lash of said Wheel. `The escapenient device or lever 74T is curved or circiilarlv" foi-med to partly encompass the ratchetk `anvheel and at' its end opposite the pawl`78 is'y engaged by the end ofthe member so as to move the member 76 on its pivot. The member 75 has its end 85 projecting in the path of a movable bar or device 86 to be hereinafter referred to, and as said bar 85 is moved it will force the member 76 on its pivot`79. -The member 75 is pivoted'at 86, Figs. 5 and 6, to the bracket 7 3 and has one end hooked and engaging one end of the member 76 to shift the latter when moved vertically, the norma'l position of the end 85 of said member 75 being downward. As will be seen when the escapement lever 1s moved, the ratchet wheel, through the action of the spring 48 which forces the carriage in one direction, will rotate the distance of one tooth at `each movement of the escapement device orlever 74'.

The carriage may ways. As shown the clutch member 89 of the carriage feed mechanism and escapement is slidingly held on the hub of the pinion 71 and rotates therewith and is prov vided with a flange 125, and thisliange is adapted to be engaged by an arm 126 ,of an angularslide 127 which is guided in the bracket 46, the said clutch member being normally forced into engagement with the clutch member 88 by a spring 127". angular slide 127 is provided with a. pin 128, and this pin is adapted to be engaged by a horizontally movable bal` 129. This bar 129 extends transversely at the rear of the carriage, Figs. 1 and 3. andv is held in slots in the carriage frame, and said bar A 1s normally forced one way by`a spring 130,

Fig. 3, and has lcam portions 131 which when forced by the finger or otherwise will have an upward movement so as to raise the angular slide 127 and release the clutch member 89 from the esca-pement mechanism, so'that the carriage may be automatically forced forward independently of its feed the desired distance insteadV of by a step-bystep movement, the clutch permitting .the carriage to move backward at all times.

The bracket 169 is held to the rocking rod 169a and is extended at 170, and the inner end of said bracket is adapted to rest under the bar 86, the latter being forced normally into engagement with the bracket by means of a spring 171. This bar -86 is provided with a plurality of teeth 172, which form abutments' adapted to beengaged by a tooth 173 carried by the lower end 174 of anangular'lever orarm 175, the said arm being pivoted at 176 to the transverse .bar 2 which supports the key-levers. The part 174 is notched at 177 and engaging the notch is a vibrating `universal bar 178 which extends transversely of the machine across and over each of the'levers `and `is pivotally held tovv swing upward and downward. *As will be vseen when any of the key-levens are depressed, the unlmrsa'l bar w-ill be operated be released in various THe and this will operate the lever 175, and by reason of the tooth 173 will o rate the ver` tical bar 86 :to vibrate the r1 bon and also operate the escapement lever. By reason of the teeth in the lower end of the bar 86, vthe tooth 173 of the lever 175 will engage said bar 86 no matter what position the carriage may be in as the said bar is elevated by both of the shift keys through the rod 168* and bracket 169 according to which lever is operated, said shift levers being both operatively connected to rock the rod 169* but not to the. same degree.4 The universal bar 17 8 is also operated by the spacing levers 17S which have the usual iin er bar, Sand are each provided with upward y projecting hooked portions 178b which engage` the transverse bar'2 and pivotally support said space levers. In this application many of the features shown and.described are not claimed herein, but form subject mattei' of other pending applications.
